SANITARY DRINKING-BOWL FOR STOCK.

To all whom it may concern:

Be it known that I, THOMAS LOUDEN, a

citizen of the United States, residing at F airfield, in the county ofJefferson and State of Iowa, have invented certain new and usefulImprovements in Sanitary Drinking-Bowls for Stock, of which thefollowing is a specification.

My invention relates to an improvement in sanitary drinking-bowls forstock, the object being to provide a self-closing bowl capable of beingopened by the animal wanting a drink, it being so constructed that itautomatically cuts off the water supply under normal conditions andcauses a flow of water into the bowl when the animal is drinking, aswell asthe complete draining of the bowl when not in use.

With the foregoing objects in view, my invention comprises a bowladapted to be fastened in' convenient position for access thereto, withinlet and outlet valves'both located within the bowl, and a cover hingedto one of the upper edges of the bowl so as to stand in a normallyclosed position, and having connection with the valves, whereby themovements of the cover in being opened and in closing will alternatelyopen and close the valves. It further consists of other featureshereinafter set forth and definitely defined in the claims.

In the accompanying drawings Figures 1 and 2 are sectional views atright-angles to each other;

Fig. 3 is a view showing a common application of the drinking-bowlbetween two stalls; I and 'Fig. 4; is a detail.

A, represents the bowl preferably made of cast-iron in any approvedshape, as for instance that illustrated; B, is a cover or lid hinged atone edge to an upper edge of the bowl, as at 1; C, indicates thewater-inlet pipe for supplying the bowl; and D, is the outlet-pipe fordraining the water therefrom. The free edge of the lid '13 is extendedbeyond the edge of the bowl to entirely cover it and to enable an animalto lift the lid with its nose.

E, indicates a lever fulcrumed at 2, and having a valve F at one end foropening the inlet-pipe C, and a valve Gr at the other end for closingthe outlet-pipe D. A spring 3 surrounds the latter valve G, it beinginterposed between the lever and the bottom of the bowl Where itnormally forces the Specification of Letters Patent.

end ofthe-lever upward, beneath which it is placed, to allow any waterin the bowl to escape through outlet-pipe D, and serving as a strainerto catch any particles whichwouldtend to clog the outlet, while holdingthe opposite end of the lever E down and closing the valve F securelyagainst its seat, thus shutting off the inflow of water.

In the form illustrated, the lid B is connected by a rod H to the end ofthe lever E having the valve, F, whereby this end of the lever will beraised when the lid is lifted on its hinges 1. This will open the inletvalve F to admit water to the bowl through the supply pipe C, and willclose the outlet valve G to hold the water in the bowl.

lVhen the lid is released it will drop of I its own gravity to itsclosed position, which will close the inlet valve F and stop the inflowof the water, and will open the outlet valve G and let the water in. thebowl pass out through the outlet D. The spring 3 will assist in thislatter operation of closing the valve F, and opening the valve G, but ifdesired, the spring may be discarded and the gravity of the lid bedepended on to accomplish this result. I

.To get a drink, the animal raises the cover B with its nose, whichoperation opens the inlet valve Fand admits the water which is Ysupplied through thepipe C in any suitable manner, and at the same time,the. outlet valve Gris closed to hold the water in the closes the inletvalve and shuts off the inflow of the water while it opens the outletvalve to let the surplus water drain off, the valves being assisted intheir operations by the spring 3.

An overflow member which may be a pipe I is in communication with theoutlet D so that in case the animal holds the valve F open withoutdrinking as fast as water is supplied, it will overflow into the top ofpipe I and out through outlet-pipe D before overflowing the edges of thebowl.

While it is evident the bowl may be placed in any chosen position, inFig. 3 I have shown it attached to the stall posts between twostanchions in a cow-barn.

The valves Gr and F are both located within the bowl, and preferably, inan open portion thereof, instead of one or both of them being locatedoutside of the bowl, or in a compartment or compartments connectedtherewith.

Constructed in this way, all parts of the bowl can be easily reached andcleaned. Consequently the places where dirt and debris can collect andbe diflicult to remove are reduced to a minimum, and the bowl will beeasily kept in a strictly sanitary condition. All that isnecessary toclean it, is to open the cover and let in some water, at the same timescrubbing it with a brush or broom, and then let the cover drop, whenall the water in the bowl will drain off through the outlet valve. A

More or less slight changes may be resorted to in the form andarrangement of the several parts described without departure from thespirit and scope of my invention, and hence I do not wish to be limitedto the exact construction herein set forth, but

I claim:

1. A sanitary drinking bowl having a hinged lid extended beyond the edgeof the bowl to enable an animal to lift it with its nose, an inlet valveand an outlet valve, both located on the bottom of the bowl, and aconnection between the valves and the lid,- whereby the openings-of thelid will open the inlet valve and close the outlet valve, and theclosing of the lid will close the inlet valve and open the outlet valve.

2. A sanitary drinking bowl having a hinged lid extended beyond the edgeof the bowl to enable an animal to lift it with its nose, an inlet valveand an outlet valve, both located within the bowl and near the bottomthereof, and a connection between the valves and the lid, whereby theopening of the lid will open the inlet valve and close the outlet valve,and the closing of the lid will close the inlet valve and open theoutlet valve.

8. A sanitary drinking bowl having a hinged lid extended beyond one edgeof the bowl, inlet and outlet conduit pipes attached to the bottom ofthe bowl valves to open and close said conduit pipes, and a connectionbetween the lid and the valves, whereby the opening of the lid will openthe valve of the inlet pipe and close the valve of the outlet pipe, andthe closing of the lid will close the valve of the inlet pipe and openthe valve of the outlet pipe.

4. A sanitary drinking bowl having a hinged cover, an inlet, an outlet,valves therefor, a lever connecting the valves, and means extending tothe cover, from the connection between thevalves, whereby, when thecover is moved, one valve is opened and the other is closed.

'5. The combination with a bowl, a cover hinged thereto, inlet andoutlet pipes, valve-seats at the upper ends thereof, a lever pivotedwithin the bowl and carrying valves, one for each valve-seat, a springfor actuating the lever, and a rod extending from the'lever to thecover, whereby as the cover is moved the valves are controlled.

6. The combination with a drinking-bowl having inlet and outlet-pipes,valve-seats for each of said pipes, and a lever carrying a valve foreach valve-seat, a spring interposed between the lever and the bowl andsurrounding one of the valve-seats, whereby to hold the lever in onedirection and acting asa strainer above the valve-seat, a hinged cover,and means extending from the cover to the lever, whereby as the cover ismoved, the lever is operated.

In testimony whereof I aflix my signature, in the presence of twowitnesses.
